SHADE-ROLLER.

SPE ZIFICATION forming part of Letters Patent No. 284,543, dated September 4, 1883.

Application filed July 6, 1883. (No model.)

specification, reference being had to the accompanying drawings.

This invention relates to rollers for windowshades; and it has for its object to providea simple and efficient roller which may be readily adjusted to windows of various widths, as will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, Figure 1 is a perspective view of my improved shade roller, and Fig. 2 is a longitudinal sectional view of the same. I I

The same letters refer to the same parts in both figures. V

A in the drawings designates an. ordinary shaderoller, the end of which is provided witha longitudinal recess, B, and with one or more slots or kerfs, O G, slitting the outer ends of the walls of the said recess longitudinally. I

D is a cylindrical block forming an extension of the roller A, and having a pin or plug, E, adapted to enter and fit in the opening or recess B of the said roller. The said pin or plug should be of such lengththat the extension-piece Dmay be moved out any desired distance to fit the roller to windows of a greater width than the roller A' might be otherwise adapted to. To retain the extension-piece D securely in position when adjusted, I provide a sleeve, ll, adapted to fit upon the recessed and slotted end of the roller A, where it serves to clamp andhold the plug E of the extensionpiece, which has been inserted into the recess B of the roller.

The slits or kerfs 0 should be only of sufficient length to enable the clamping-ring to operate successfully; but the recess B may extend nearly through the entire length of the roller. By this construction the roller is not materially weakened, and is yet capable of being extended to nearly twice its length when folded.

The operation of my invention will be readily understood from the foregoing de scription, taken in connection with the drawings hereto annexed. Much difficulty has heretofore been experienced in fitting shaderollers, especially of that kind which are equipped with auto matic winding-springs, to the windows for which they are intended. By

kinds of rollers, all such difficulties are overcome, as the roller may, in a momentstime,"

be fitted or adjusted to any window. The construction is simple, andmy improved roll er may be produced at a cost hardly exceeding that of ordinary curtain-rollers. I claim and desire to secure by Letters Patent of the United States The roller A, having recess B, extending nearly through its entire length, and slots or kerfs O, slitting the walls at the outer end of said recess, in combination with the extensionpiece D, having pin or plug E, and the sleeve or clamping-ring F, substantially as herein described, for the purpose shown and specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
